Every day, it is easy to see advertisements in English all around us. Look at your own bags and clothes, and at the bags and clothes of your classmates. How many different advertisements can you see which use English words?

Often bags and clothes show the name of the company that made them. This is a popular form. A special picture or symbol called a lo go(标识语)is sometimes used. Logos appear on many different products(产品). They are popular because when you see a logo, it is hard to forget that product or company.

    It is common to see advertisements on TV and hear them on the radio. Most advertisements are very short. Sometimes the advertisers use a short sentence which is easy for people to say and remember. Nike, for example, has a simple English sentence which is used all around the world: “Just do it.” Advertisements often use funny situations as well. It is simple to remember it.

    All advertisements are designed(设计) to make people buy a product. An advertisement for a soft drink, for example, might show a group of young people who are having fun. The young people are all drinking the soft drink. Advertisers are saying to you, “Why don't you buy this drink and be like these people? You can be young and modern.”

    You might think that advertisements are not after you, but next time you buy a soft drink, ask yourself this question: Why am I buying this particular(特别的) product?

Ray was thought to be a strange boy. One day when he was flying his kite, he said to himself," Did anybody ever try to fly a kite at night? I think it must be very fun. But the kite can't be seen in the dark. What if I tie a light to it? That would be really good. I {#blank#}1{#/blank#}(try) it tonight."

As soon as it was dark, he {#blank#}2{#/blank#}(take) his kite and lantern, and went to a large field about a mile from his home. He tied the lantern to the tail of his kite. The lantern {#blank#}3{#/blank#}(make) of paper. The kite flew higher and higher. He tied the string (线)to a tree, and then he stood there, staring at his kite. It floated (飘) high up into the air. How wonderful! While Ray {#blank#}4{#/blank#}(enjoy) his special kite, some people in the village also saw it.

"Look! A light{#blank#}5{#/blank#} (fly) in the sky," one person said. "It can't be a light," said a man.

"Perhaps it's a big firefly (萤火虫) ,"said another,

"Maybe it's a comet (彗星),"said another man.

"How strange!" said a boy.

"Let's find out what this strange light{#blank#}6{#/blank#} (be)," the last one said. Then they went to the field.

Ray, who had gotten tired of standing, was sitting behind a tree. He{#blank#}7{#/blank#} (see) the men as they came, but they didn't see him. When they reached under the light, and saw what it was, they looked at each other and said, "There is nothing unusual {#blank#}8{#/blank#}(happen)! This is just a trick of some naughty boys, but it {#blank#}9{#/blank#} (fool) us all.

Let's keep the secret. "Then they laughed and went back to the village. When the men had gone, Ray thought it was time for him {#blank#}10{#/blank#}(go), so he went home, too. When his mother heard what he had done, she hardly knew whether to laugh or scold (责备), but just told him to go to bed.

Since humans sent the first satellite（卫星） to space in the 1950s，scientists have been studying an important topic：how to grow plants in space if humans live there one day.A recent experiment at the Tiangong space station makes a big step forward.

Chinese astronauts have successfully grown rice seedlings（幼苗） during the Shenzhou XIV mission.The researcher said，"The rice seedlings are growing very well."Since the rice experiment began on July 29，the seedlings of the tall shoot rice variety（高杆水稻品种） have reached a height of 30 centimeters.The seedlings of the dwarf rice variety（矮杆水稻品种） have grown to 5 centimeters，China Daily reported on August 30，2022.

While there have been other rice experiments in space，this one is the first of its kind to produce the complete life cycle of a plant—it begins with a seed and ends with a grown plant producing new seeds.

Such food﹣growing experiments are not for astronauts.They can solve food problems on Earth.By sending seeds to space，we can create mutated（突变的） seeds that can produce higher yields（产量）on Earth.

For more than 30 years，China has developed over 260 new types of seeds in space.They are planted on Earth every year.

According to Yao Tong，an engineer from Hainan Aerospace Engineering Breeding Research Center，30%of strawberries sold in Beijing are "space strawberries"，which are as big as eggs.The center has also produced "space tomatoes"with yields increased by 30%，and "space bananas"with a growth cycle shortened from 13 months to 9 months.

Big schoolbags have been a big problem for students for a long time. Maybe 1 schoolbag is too heavy to carry, and it troubles you a lot2 you want to take out a book to read. Now e-textbooks will 3 you.

It is said that many Chinese middle schools are going to use e-textbooks. An e-textbook, in fact, is a small computer 4 students. It is much lighter than a usual schoolbag and5 to carry. Though it is6 small as a book, it can hold(容纳) everything for study. The students can read the text page by page on 7 screen, take notes 8 the special "pencil", or even "hand in" homework to their teachers by9 emails. All they have to do is press a button(按开关).

Some people say e-textbook are good,10 some say they may be bad for the students' eyes. What do you think of it?

Do you have a sleep problem? If you do, here is a simple way to help you improve your sleep. You may need to see more sunlight, especially in the morning, according to a study.

A team of researchers from New York, US did the study, reported Yahoo Nows. The team did  a study on 109 office workers across the US. Some of the workers saw lots of light during the morning hours, between 8 a. m. and lunchtime. The researchers found that these workers had a better sleep than other workers. They also fell asleep more quickly at night.

Why is sunlight so important to our sleep? Researchers say it helps us set our" body clock". When there is less and less sunlight at the end of the day, our body starts to make melatonin(褪黑素). It makes us feel sleepy so that we know it's time to go to bed. Our body makes the most melatonin at night. But during the day, sunlight tells our body to make less melatonin so that we can stay awake and do our work.

Researchers suggest that we should see fifteen minutes of sunlight in the morning. It can help balance the melatonin in our bodies.

A boy helped save the life of his friend from choking(窒息) in the dining hall at school while having their lunch there. Many people watched the video of the accident on the Internet. 

In the video, the new student Jackson just got a seat and ate his chicken sandwich. Suddenly the food stuck(卡住) in his throat and his face turned red. Hunter Olsen sat across from Jackson. He thought that Jackson was just joking and laughed at it along with his friends. But soon it became clear that Jackson was really choking and tried to cough the food out. He pointed to his throat to tell Hunter that he was not playing. Hunter realised that he had to do something and used the Heimlich manoeuvre(海姆利克急救法). Finally, Jackson coughed the food out and could breathe again. 

Ms Howa, who taught them the Heimlich manoeuvre during her health class, said she couldn't believe her ears when she heard what happened. But she was over the moon to know that her student put what she taught into practice.She was so proud of Hunter. 

Hunter said he wasn't interested in Ms Howa' class because he thought he would never use it in his life, but her great teaching helped him know what to do when in trouble. Then he said, "I just thought that doing something was better than doing nothing. "
